2031527 9013421 PCTABS00002 Self-reinforced polymer composites of 60-5 percent by weight of an at least partially crystalline high performance thermoplastic polymer and 40-95 percent by weight of a melt processable wholly aromatic polyester which exhibit anisotropic properties in the melt phase. This wholly aromatic polyester is a liquid crystal polymer, or LCP. The high performance thermoplastic polymer has a melting point of at least 200·. Polyether etherketone is a preferred at least partially crystalline polymer. The wholly aromatic polyester is in the form of predominantly unidirectionally oriented continuous fibers primarily in the range of about 1 to 10 micrometers in diameter, distributed in a matrix of polyether etherketon. The polymer composites of this invention have high tensile strength, high modulus, satisfactory elongation, good impact strength, and good high temperature properties.
